Application led March 13, 1916. Serial No. 83,840.

To @ZZ inkom t may concern Be it known that I, JOHN KAROLL, a subject of the King of Hungary, residing at Flint, in the county oi Genesee and State of Michigan, have invented certain new and useful Improvements in Butter Pressing and Molding Machines,of which the following is a specification.

This invention relates to new and useful improvements in butter pressing andmold-y ingmacliines.

The primary objectof the invention is the provision of -a suitably refrigerated press adapted -for extracting the moisture from butter and packing a predetermined quantity thereof in a` mold for ready removalfrom the press for purposes of use and sale.

A further object `of the inventionis the provision of a press for packing butter4 arranged witli acutting'device for separating the body of butter with a desirable portion thereof filling a removable mold member.

A still further object is to provide a butter packing device that is easy and inexpenx sive to manufacture but which possesses eX- treme strength having the' parts thereof easily removed for cleaning and arranged with a refrigerant chamber for maintaining the butter in a cool condition while being operated upon. l

l/Vith the general objects in view and others that will apk ,ar as the nature of the invention i@ better understood, the saine consists inthe novel combination and arrangement ofparts 'hereinafter fully described, illustrated in the accompanying drawings and then claimed.

In the drawings forming a part of this application aiid in which Alike ydesignating characters refer to corresponding parts throughout the several views Figure 1 is a central vertical sectional view of the device. I

Fig. 2 is a side elevation thereof partially shown .in vertical central section upon a plane at fright, angles to the line of section shown in Fig. 1., i

Fig. 3 is a top plan view of the device;A

Fig. 4 1s a transverse sectional view taken upon line IV-IV of Fig. v1 before the nlold-` ed butter has been severed.

Fig. 5 is a similar view after the butter cutting member has performed its operation.

Fig. 6 is a transverse sectional view taken upon line VI-VI of Fig. 1, the 'fmolding being shownin dotted lines partially removed from themachine. i

Fig. 7 is a vertical transverse sectional view taken upon linel VII-V l1 of Fig. 4,

and Fig. 8 illust ates by planand vsectional detail views the manner of mounting the ends of the` butter cutting wire.

The present machine is arranged for pressing, packing and molding quantitiesof butter and providesl an outer cylindrical casing 1Q mounte'ifl upon suitable legs 11 be. neath the bottom 12 of the casing while a4 butter receiving tube 1??, rectangular in cross section, is centrally arranged upright within the casing 1 0. l

An annular diaphragm or falsepbottomvll'i is arranged within the said casing spaced ,above and' in parallelism with the bottom v1-2 and having the tube r13 extending therethrough, the portion 15 'of the said tube be-i low the diaphragm 141 terminating substan- A rectangular block form of vplunger or being vertically movable therein an au-Xiliaryfpositioned stem 18hav1ng teeth itially midway between the said diaphragm 'piston 17 is arranged within the tube 13 by means of 19 upon one `edge thereof and thus constitut-ing a tooth operating rack for the said plunger.' A removable lidl or cover 20circular inform is provided for the casing 10 having a depending annular flange-21 adapt-V ed for fitting within the open upper end of the casing,- pivoted locking bolts QQhaving set nuts 23 thereon being arranged for len gag'ing slotted oppositely arrangedglugs 24: of the lid 20 in the usual manner. The lid j projectingO l opening '26 therethrough with a bearing washer 27, the' 20 is provided with a centrally boss 25 'having a rectangular stem 18 being freely slid'able through v` the said `washer and opening. l ,I

Anoperating shaft 28 is transversely j'o'iir naled through the casing 10a-nd has a-piriioii 29 centrally: secured thereto in mesh. with the stem teeth 19 when the plungerl is .positionedrwithin the tubey 13 and thejid 20 is in position upon the casing. yThe" gear 30 is provided upon an outwardly extending end 31 of the shaft 28 while a sprocket chain 32 connects the gear 30 with a relatively large gear 33 mounted upon a stub shaft 34-projecting from the casing at a point be,`

neath thecshaft extension 31. A removable operating crank is provided for the stub. shaft 34, it being evident that by turning the crank 35 fQroper-ating the shaft 28 in oneYJ direction, tlie stem 18'and plunger 17 will" be forcibly depressed while the stem and plunger will be elevated upon a reversal in the turning direction of the said crank.

A mold 3 6 in the form of a drawer or slide is arranged within the casing 10 beneath and in alinement with the lower end portion 15 of the tube 13, the said slide having a pull knob or handle 37 whereby the mold 36 may be withdrawn and inserted when desired.

The mold 36 is in the form oi a rectangular frame open at both sides and slidable upon the casing bottom 12 and when in its operative position as illustrated in Fig. 1 of the drawings is arranged for receiving the butter 38 which is forcibly packed therein by means o1" the descending plunger 17.

Opposite parallel guide plates 39 are arranged at opposite sides of the mold 36 and between which guides the mold is adapted to slide while an arch-shaped cutter frame 40 has its opposite legs 41 slidable in longitudinal grooves 42 in the upper edges of the said guides 39. i

Teeth 43 are arranged upon the upper edges of the legs 41 and a transversely arranged shaft 44 extends through the casing 10 and is provided with pinions 45 in constant mesh with the said teeth. A." out-l wardly projecting encl46 ofthe shaft 44 is adapted to reeeiveft le aforementidd crank 35 whenever desired for the purpose of turning the shaft 44 and thus slidably moving the cutter frame 40 inwardly and out- Wardly of the casing.10, it being noted that the outer end of such cutter frame is of the same curvature as the adjacent side of thel casing.

The inner ends of the legs 41 kare provided with transverse alining perforations T47 through which aabutter cutting wire 48 is extended and secured to the said legs 41 by means of screws 49. When the cutter frame .is normally positioned inwardly, as best illustrated in Fig. 1 of the drawings, the same i's slightly to the rear of the butter column 38 and in horizontal alinement with a slight space between the upper edge 50 of the mold 36 and the *lower end mouth 16 of the butter 'feeding tube portion 15. By turnf ing the ,crank 35 when positioned upon the lower shaft 46, the cutter frame 40 is forced outwardly, thus drawing the cutting wire 48 through the butter 38 between the mold and the tube portion 15, thesaid wire 48 .assuming tlreV position illustrated in Fig. 5

narrare@ .V removablel plugs 51 at any desirable point for allowlng access to the interior of the casing adjacent the guides 39 for the purpose of effecting repairs in the cutter wire '48. The lower extension 15 of the tube 13 is provided upon its forward side with a bottom edge extending lower than the other sides of the said tube and acting as. an abutment for the cutting wire 48 as shown in Fig-15jv The 'complete operation of the invention will be apparent from the within detailed description thereof, it being noted that the annular chamber 52 between the tube 13 and the casing 10 is employed for the reception of. ice togool the butter within the tube 13, a faucet 5,3 being arranged adjacent the bottom-of the chamber 52 for drawing off the water therefrom outwardly through the side of the casing 10. lVith the mold 36 pobringing the pinion 29 in mesh with the stemv gear 19 provides for exerting a downward pressure upon the butter 38 by turning the crank 39 when attached to the stub shaft 34; The moisture is thus extracted from the butter and the butter is packed into the mold 36 completely filling the same and whereupon the crank 35 is positioned upon the shaft 46 and the cutting wire 48 drawn through the butter even with the upper edge of the mold 36, which mold is then removed by means of the pull knob 37 for extracting the butter block so molded. r1`he cutter frame 40 may then be returned to its normal position and after replacing the mold 36 more butter may be packed into the same by repeating the operation. It will be seen that the forward plate 54 of the forward connecting portion of the mold 36 to which the knob 37 is attached having a curvature corresponding to that of the casing 10 which together with the forwardvbar of the cutting frame 40 are in alinement with the side wall of the casing when the cutter frame and' casing, a removable lid therefor, a butter-j receiving tube axially mounted in the said casing and providing a refrigerating chamber between the said tube and casing, a

packing plunger operatively arranged Within said tube and a removable butter-receiving mold'arranged Within the'casing beneath said tube, parallel upstanding guides at opposite sides of the mold in frictional contact therewith, a U-shaped cutter frame having the legs thereof slidably mounted upon said guides, a .cutting Wire carried by the-frame and having a path of movement transversely of the llane o said tube and mold and intermediate thereof, rack teeth on the upper sides pf said frame legs,'a transverse shaft journaled through' the casing, operating pinions y/upon the said shaft in mesh with said racks, and an operating crank upon the` shaft exterioryly off said casing.

In testimony whereof I ailix my signature.
